Can't load my extension as an operator in RM

wujiang

Hello,

I just follow the "hew to extend rapidminer 5" paper, when I finish a operator cloass, creat and move a '.jar' into plugins folder, I can't see my operator in the left side "operators" menu when I excute my Rapidminer(Unuk). I am not sure that cause the build.xml or operator.xml?

here shows some informations:

Thanks for your help.

Hi,

make sure you have a build.properties next to your build.xml which looks like this:

extension.version=5
extension.revision=3
extension.update=000

When launching RapidMiner from within your IDE, you should see in the log that your extension is loaded (or why it is not).

Regards,
Marco

I have the same problem
and none of this solutions worked for me.
please help!

Hi,

let's say you're having RapidMiner Studio in your IDE and launch it from there. To have it load extension, the extension .jar files must be in the /lib/plugins folder of the project. For example, for me currently the path is "C:\Users\boeck\git_repo\rapidminer\lib\plugins", where "rapidminer" is the folder which Eclipse uses as the project folder.

Regards,
Marco
